Everybody hates it, but everybody does it. A recent report said that 40%of Americans hate tipping. In America alone, tipping is a $16 billion-a-year industry. Consumers acting politely ought not to pay more than they have to for a given service. Tips should not exist. So why do they? The common opinion in the past was that tips both rewarded the efforts of good service and reduced uncomfortable feelings of inequality. And also, tipping makes for closer relations. It went without saying that the better the service, the bigger the tip.
But according to new research from Cornell University, tips no longer serve any useful function. The paper analyzes numbers they got from 2,547 groups dining at 20 different restaurants. The connection between larger tips and better service was very weak. Only a tiny part of the size of the tip had anything to do with the quality of service.
Tipping is better explained, by culture than by the money people spend. In America, the custom came into being a long time ago. It is regarded as part of the accepted cost of a service. In New York restaurants, failing to tip at least l5% could well mean dissatisfaction from the customers. Hairdressers can expect to get l5%-20%, and the man who delivers your fast food $2. In Europe, tipping is less common. In many restaurants the amount of tip is decided by a standard service charge. In many Asian countries, tipping has never really caught on at all. Only a few have really taken to tipping.
According to Michael Lynn,the Cornell papers’ author, countries in which people are more social or outgoing tend to tip more. Tipping may reduce anxiety about being served by strangers. And Mr. Lynn says, “In America, where people are expressive and eager to mix up with others, tipping is about social approval. If you tip badly, people think less of you. Tipping well is a chance to show off.”

When I looked at the grade on my math paper my jaw almost dropped to the ground: a big “65” in bright red ink. I had never received such a terrible grade before.
I was so ashamed that when I got home that afternoon I lied to my dad. I told him I got 85 and that the report wouldn’t come until the end of the month. Dad smiled. His daughter would never lie about her grade, so he didn’t doubt the unusual delay of my report.
A month later, Dad casually asked me again about the report at the dinner table. He looked right into my eyes and asked for an answer. Having no choice, I told him that I had in fact got just 65 in my math final. I had lied because I didn’t want to let him down.
For a moment, he just looked at me. I would have preferred a telling off than that silence. Finally, Dad said, in a hurt voice, “You have already let me down, with your lie. I am not disappointed at your math score. That is no big deal – no one can be perfect all the time. But I am very disappointed in you. If you can’t be honest with your dad, who can you be honest with? It’s much easier to achieve a better grade than rebuild someone else’s trust in you.”
Dad’s words touched my heart. I couldn’t forgive myself for having hurt his feelings. I took out the report that I had been hiding for weeks, handed to him and apologized, sincerely. I realized that my honesty is not only important to me personally, but to those around me that truly care about my well-being.
In one of Shakespeare’s plays a character says: “No legacy is so rich as honesty.” After the crisis between Dad and me, I began to understand those words.

The disaster at the Chernobyl(former USSR前苏联) power station happened quickly and without warning. It was in the early hours of April 26, 1986 when the cooling system of the reactor(反应堆) failed. Minutes later, a violent (猛烈地) explosion blew the top off the reactor and blasted(爆炸生成) a huge cloud of radioactive gas high into atmosphere. Two people were killed immediately. Hundreds received powerful radiation overdose (过量). And more than 25,000 had to be taken away from their homes.
Days later, the radioactive cloud had spread as far as Scotland. Its radiation was weak, but all over Europe radioactive rain was falling. In some areas people were advised not to eat fresh vegetables, or drink fresh milk, and the sale of meat was forbidden.
The accident at Chernobyl was the world’s worst nuclear accident. In Britain, it convinced (使……相信) many people that all nuclear power stations should be shut down for good. But the Central Electricity Generating Board didn’t agree. They claimed that ·similar disasters could not happen in Britain because of safer designs, fewer deaths are caused using nuclear fuel (燃料) than by mining for coal or drilling for oil and gas. Nuclear accidents are unusually fewer compared with other types of accidents-such as air crashes, fires or dam break-down more nuclear power stations are necessary because the world’s supplies of oil, coal and natural gas are running out.
In 1957 in Cumbria (Britain) a nuclear reactor overheated and caught fire. No one was killed but fourteen workers received radiation overdose. Small amounts of gas and dust were let out over the local countryside.
An official report said the accident was nearly a full-scale disaster. The Nuclear Authority wanted the report published but the Prime Minister at the time refused. He thought that it would make people less confident in Britain’s nuclear industry. Thirty years later, the cabinet(内阁) records of 1957 were published. Only then did the public discover what had really happened in Cumbria.
【小题1】. One result of the Chernobyl nuclear disaster was that ______.

A.25,000 people were killed
B.fresh foods were polluted
C.people in Scotland were taken away from their homes

【小题2】.According to the passage, nuclear accidents______.
A.are most unlikely to cause deathB.are always kept secret from the public
C.can only happen in underdeveloped countriesD.may happen in any country that has nuclear power station.
【小题3】. After the nuclear accident at Chernobyl many people in Britain _______.
A.still believed it could not happen in their country.
B.were not convinced that nuclear power stations could be safe
C.accepted that there would be fewer deaths than in drilling for oil
D.supported nuclear power stations because world fuel supplies were low
【小题4】.. The British Government refused to publish the report on the Cumbria accident because _______.
A.Britain’s supplies of oil, coal and gas were running out
B.it takes thirty years for the effects of radiation to appear

D.it was concerned that the British people would doubt their country’s nuclear expertise (核技术)

WILD WEATHERMAN
Name: Sam Champion
Hot job: TV Weatherman
Where: ABC-TV, New York City
When you were a child, did you plan to forecast wind, rain, and snow on TV?
I wanted to be a foreign journalist. I took courses in weather science at Eastern Kentucky University, but I majored in broadcasting news.
How did you finally become a weatherman?
My first job in the early 1980s was at the local TV station in Paducah, Kentucky. I did everything from turning on the lights in the morning to writing and delivering morning news. I put together weather forecasts, and became interested in them.
Back then, how did you forecast weather?
Independent companies collected computer information that showed, for example, how a single weather system might split into snow or snow mixed with rain. The information was often opposite and the job of a weatherman was to study the information and make the best educated guess about the storm.
Has weather forecasting changed much with new technology?
Advanced computers, satellites, and Doppler radar (sound waves used to track storms) have made forecasting more exact. But we still know very little about how weather is shaped. So far, we just have theories.
 Any advice for children who’d like to become weather scientists?
To me, weather is the most exciting field in the world. There are still so many more questions about weather than answers. After all, if we can’t foresee floods or hurricanes, how safe a society are we? Weather forecasting is wide open for scientists who love to solve puzzling problems. The next generation of meteorologists (weather scientists) will unlock many of Earth’s weather secrets. So get a general knowledge of Earth science, and study meteorology in college.
   Thanks, Sam.

This is a dangerous world we live in. The number of murders goes up every year, people are dying of cancer, more people contract HIV, more teens are using drugs, etc. You know this because you have heard all the statistics on the news and in the paper.  But do you really have an accurate idea what they mean? The numbers are growing up, but how do they compare to the growth in population? Are more cases of these diseases being reported because of better testing techniques, or are the diseases more common? The fact is that without knowing the background statistics mean very little.
This growing trend of reporting only part of the information is becoming dangerous. For example, several years ago a high school student reported the dangers of the chemical known as dihydrogen monoxide. This chemical, found in most cancerous tumors(肿瘤), is often found in the blood of people drunk on alcohol, and causes complete physical and mental dependence for those who take the chemical even once. After reading his report, more than 75% of his Advanced Placement Chemistry class voted to forbid this dangerous chemical! Every one of the above statements is true, yet this chemical is necessary to all life on earth. The students made the mistake because they voted knowing only a few statements and statistics, rather than the chemical’s full background.
The point of this article is that one should be aware of what is and is not being said. When one finds a new fact or number, one should try to consider other important information before forming an opinion with only half-truths. Always remember that the author is trying to convince you of his or her own view, and will leave out information that is different to his view. For example, look again at the statistics that suggest skiing is safe. Only 32 people may die each year when skiing, while 897 die from lightning strikes, but which is really the most dangerous? If you think about it, you realize far fewer people go skiing each year than the number of people who are in danger of a lightning strike. When you think about it, skiing is more dangerous than you might at first think when looking at statistics. If we teenagers are to be left in this world, we had better be able to think critically, and form our own views, rather than be easily persuaded by another’s. To be warned is to be prepared.
59. In the first paragraph, what problem does the writer want to warn us?
A. We are now living in a dangerous world.
B. We get a lot of false statistics from the media.
C. Statistics alone without full background doesn’t give us an accurate pictures of things.
D. There are around us more and more murders, diseases, etc.
60. Why does the writer use the example in the second paragraph?
A. To argue that high school students are easily persuaded.
B. To show the danger of reporting only part of the information.
C. To prove what is necessary to us might be dangerous.
D. To warn us of the harmful substance around us.
61. Relative information is often left out because__________.
A. Relative information is not that important.
B. too much information will make readers feel confused.
C. the author is trying to show what he or she says is true.
D. readers are not able to analyze so much information at once.
62. What can we learn from the passage?
A. We should learn to think critically and look at problems from all sides.
B. Some measures must be taken to protect our dangerous world.
C. The growing trend of reporting only half-truths is getting out of control.
D. Teenagers ought to improve their ability of telling right from wrong.
